Brake, Fuel & Transmission Line Fittings

AGS fittings connect and seal the brake, fuel, power-steering, and transmission lines on virtually any vehicle. Whether you're finishing a brake-line repair or splicing a fuel line, the right fitting — matched to your line size, flare type, and thread pitch — is what keeps the connection leak-free under pressure.

Shop AGS Fittings by Type

From inverted-flare and bubble-flare hardware to adapters and quick connects, AGS fittings cover the full repair: brake line adapters, connectors & adapters, tube nuts & unions, compression unions, quick connects, power steering fittings, and labeled fitting assortments.

Why AGS Fittings?

Every AGS fitting is engineered to OE tolerances for a secure, leak-resistant seal and quick installation. A loose, mismatched, or corroded fitting causes fluid leaks, soft pedal feel, and reduced braking performance — so each one is easy to match by line size, flare, and thread pitch, with no guessing at fitment.

Banjo Fittings & Bolts

For hydraulic hose connections, our banjo fittings and banjo bolts ship with fresh copper crush washers for a proper seal, and power-steering banjo fitting assemblies are available in M14x1.5, M16x1.5, and M18x1.5.

Get the Right Fit

Not sure what you're matching? Keep common sizes on hand with a labeled fitting assortment, and turn corroded flare nuts without rounding them using a ratcheting line wrench.
